Problems solved by technology

At present, domestic research on fermented soybean hulls is rare, and the fermentation technology is not mature enough
Although there have been some related reports, the main reason is that part of the fermentation process is complicated, requiring strict control of the fermentation process conditions in multiple stages, and the fermentation cycle is long; this also leads to a certain degree of limitation in the large-scale promotion of these technologies in the field of fermented feed
In addition, some of them mainly focus on a certain stage of the enzymatic hydrolysis or fermentation process, while ignoring the impact of the overall fermentation process on product quality, resulting in unstable product quality, incomplete treatment of anti-nutritional factors, poor feed conversion rate, and beneficial to the product. There are problems such as significant differences in the content of microorganisms and beneficial nutrients

Abstract

The invention provides high-dietary-fiber and low-antigen-protein fermented soybean hulls. The soybean hulls are prepared by fermenting 55-70 parts of soybean hulls, 5-20 parts of a bacterium-enzyme synergistic fermentation agent and 25-40 parts of distilled water based on a bacterium-enzyme synergistic fermentation technique, and are applied to pig feed at different growing stages of sows, piglets, fattening pigs and the like. According to the fermented soybean hulls, the attraction and palatability of fermented soybean hulls can be improved, the feed utilization and economic benefit can be improved, and the sustainable development of the breeding industry can be promoted. The method for preparing the fermented soybean hulls has simple operation, high fermentation efficiency and short fermentation time, can effectively save a feed formula space, reduce feed cost, greatly increase the nutritional value and feeding value of soybean hulls and the utilization of soybean byproducts, sufficiently utilizes unconventional feed resources and prevents environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of biological fermentation, and in particular relates to fermented soybean hulls with high dietary fiber and low antigenic protein and a preparation process thereof. Background technique [0002] Studies have shown that dietary fiber diets can solve some problems in different growth stages of animals, such as diarrhea in piglets and constipation in sows. But at present, my country's unconventional feed resources rich in dietary fiber are not fully utilized, including soybean hulls. As the main by-product of soybean oil and meal, soybean hull is a new unconventional feed resource, which has been widely concerned because of its high fiber and high energy characteristics. Soybean hulls are mainly the outer coating of soybeans, which are mainly composed of cellulose, hemicellulose, lignin and pectin. They have high dietary fiber content, low moisture and lignin content, high digestibility, and amino acid conten...
